COLLAPSIIBLE FIELD-CHAIR. I

To all whom it may concern. 1

Be it known that I, J OHN HAYDUK, a subject of the King of Hungary,

of New York, have invented new and useful Improvements in Collapsible Field-Chairs, of which the following is a specification.

My invention relates to portable chairs of the folding or collapsibletype- It provides a chair of this character which is of simplemanufacture, and is so constructed that it folds up into such a smalland conveniently shaped bundle that it can be carried around by a personwithout the slightest discomfort.

Referring to the drawings in which I have illustrated the preferred formof my invention:-I igure l is a side view of the collapsible or foldingchair constructed accord ing to my invention. Fig. 2 is a top, plan viewof the same with the flexible seat cover broken away for the purpose ofshowing the details of the joint. Fig. 3 is a side-elevational view ofthe chair in the folded position. Fig. 4 is a bottom plan view of thedisk member in which the legs and seat stays are journaled. Fig. 5 is adetail view of a portion of a seat stay with the fastening elementattached thereto.

Throughout the separate views the same part is designated by the samereference character.

Referring to the drawings annexed hereto and forming a part of thisspecification; the disk 1 carries four seat stays 2 suitably journaledtherein at right angles to eachother, the said seat stays 2 beingpivoted to the channel plate 3 mounted on the underside of the disk 1 bymeans of the rivets 4. Pivotally mounted at 5 on one side ofeach seatstay is an arm 6 having a flat abutting surface 7 lying in toward thedisk 1 and, at its other end, it carries a lug or pin 8. Mounted on theseat stays 2 is a split member 9 adapted to slidably move between thetwo pins 1010 carried by the stays, and also adapted to slide over theends 11 of the member 6 when said member is drawn down into position.

The outer ends of the seat stays 2 are turned upward and carry theT-shaped members 12 pivotally mounted thereto. The flexible seatcovering 13 is riveted or otherwise suitably secured to the cross barsof the T-shaped members 12, as is shown at 14. Pivotally journaled inthedisk 1 be- Specification of Letters Patent. Application filed. October22, 1913.

residing at Brooklyn, in the county of Queens and State Patented Oct.13, 1914. Serial No. 796,674.-

tweel each pair' of seat stays is a leg member 10 each member having theeye portion 16 adapted to pivotally hold the said legs in place on thepins 17 carried by thedisk l.

The lower end of each leg carries an enlargedv foot midway of each legis pivoted a supporting arm 19 carrying at its free end the bayonet slot20 adapted to engage the lug 21, also mounted on each leg.

The supporting arms, when in position, form a rectangle and join eachleg to the next succeeding leg, thereby forming a sub stantial supportfor the legs and preventing them from spreading when a load is carriedby the chair.

The parts of the chair, when folded, assume the position shown in Fig. 3and in order to set it up in the operative position, the chair is turnedwith the feet 18 upward and the legs are then pivotally swung downward.The supports 19 are. hooked over their respective button lugs and thelegs are then in position to support a load. To bring the seat portioninto the operative position, the arms-2 are brought downward until theflexiblecovering lies flat, then the members G are pulled down by meansof catching hold of the lugs 8 until the ends 7 thereof book under thesurface of the disk 1. The split members 9 are then slid over the ends11 of the members 6 and serve to retain the same in their downwardposition, as shown in Fig. 1, and also retain the seat arms 2 inposition. The chair is then ready to receive aload.

It is understood that various modifications of my invention may be madewithout departing from the spirit thereof. Having thus described myinvention, what I claim is 1. A collapsible field chair comprising incombination, a flexible seat portion, a disk member, seat supportingarms pivotally secured to said disk member, T-shaped members pivoted toand adapted to be attached to said flexible seat portion, locking armspivotally mounted on said seat supporting arms and adapted at one end toengage the upper surface of said disk, slidable member mounted on eachof said seat supporting arms and adapted to engage said locking armswhereby said supporting position, legs journaled at one end in said diskmember, a foot portion integral with arms are retained in extended,

portion 18. At a suitable point said seat supporting arms each of saidlegs, an arm pivoted to each of said legs and adapted to detachablyengage the adjacent leg whereby said legs are supported.

2. A collapsible field chair comprising in combination, a flexible seatportion, a disk member, folding seat supporting arms pivotally securedto said disk member, means pivoted to said seat supporting arms adaptedfor attaching the said flexible seat portion thereto, means pivotallyconnected to said seat supporting arms and adapted to engage said diskmember and retain said supporting arms in the extended position, legsjournaled in said disk member, and means carried by said legs wherebyeach leg may be detachably connected to the succeeding leg therebyforming a support for the said legs.

3. A collapsible field chair comprising in combination, a flexible seatportion, a disk member, folding seat supporting arms pivotally securedto said disk member, T-shaped members pivoted to the seat supportingarms and adapted for attachment to said flexible seat portion, levermeans pivotally connected to said seat supporting arms having one armadapted to engage said disk and a fastening member carried by said seatsupporting arms whereby the other ends of said levers may be retained insuch a position as to hold said lever in contact with said disk, therebyretaining said seat supporting arms in the extended position, legsjournaled in said disk member, and means carried by said legs wherebyeach leg member may be detachably connected with the succeeding legmember thereby forming a support for said legs.

a. A collapsible field chair comprising in combination, a flexible seatportion, a disk member, folding seat supporting arms pivotally securedto said disk member, means pivoted to said seat supporting arms adaptedfor attachment to said flexible seat portion, means pivotally connectedto said seat supporting arms and adapted to engage said disk member andretain said supporting arms in their extended position, legs journaledin said disk member, a foot portion integral. with each of said legs, anarm pivoted to each of said legs and having a bayonet slot in the freeend thereof, buttons carried by each of said legs and adapted to engagethe bayonet slots of said arms whereby said legs are detachablyconnected to each other and thereby supported.

In testimony whereof I afiix my signature in the presence of twowitnesses.
